I recently discover PhoneGap and Sencha, I would try this technology in order to check if in the future we can use this in our projects. I easily setup the Kichen Sink Demo in PhoneGap. Everything work great except for Orientation Change. I read on this forum and somes other and maybe I don't understand but i always see a error in result.

After the orientation change, the list is store only at the left of the screen and after i touch the screen, the list go up at the middle of the screen... I add a screenshot of the result!
